      Decent basic binding post

            Soldering tips for ALL plastic binding posts like this:

            Screw the post body into the hole of the chassis, cabinet or mounting plate. That's your instant soldering jig.

            Make sure to pre-tin both the post and the wire before final soldering (the threaded housing is plastic and will not stand up well to any more than a brief application of heat compared to solid nickel or gold posts which are not as sensitive but are VERY expensive). Use a good low-acid flux (I use it even with fluxed solders myself) on post and wire for pre-tinning. If the post doesn't tin easily use a Scotch brite pad or fine abrasive cloth to remove some of the plating scale from the post which may exist from the manufacturing process.

            Fine brush (like a toothbrush) or cloth wipe off any telltale residue from the soldering. (There are also special solder cleaning chemicals available... but not really needed.)

            An additional tip which may be helpful to make this installation pristine is to pre-sleeve each individual internal conductor with a short (about 1" worth) of shrink tubing and then shrink it over the entire post and wire up to the plastic mounting thread. For dual conductor wire, make sure to separate far enough to keep the sleeve away from the solder iron tip.

            [That's about as a neurotic a soldering regimen as anyone could want, I suppose, but it works.]

                These work fine. The dude that doen't like them is still figuring out how to use a left-handed hammer. I guess in todays world, things snap together. A solder pencil, solder, and maybe a "3rd hand tool", and you're done. Real hard.

                    I have used this type of binding post before and do not remember soldering it. Just screw the thumbnuts down on the banana plug and you are done. Rap wire around terminal and solder. Takes about five min. unless some one shows up with the beer.

                          Guy below doesn't know what he's talking about. Yes, you solder to the back of the binding post, it's not rocket science. Extraordinary solder skills aren't necessary...all you do is make a 'u' shaped bend in the wire with needle-nose pliers, place on binding post, then crimp slightly with needle-nose pliers to keep it in place and solder. You wouldn't need more than one set of hands because if you just lay the wire on and solder to physically hold it there, you're an idiot because soldering!=welding. Solder is for electrical connection, and should never be relied upon for physical connection. Wrap the darn wire around and solder. This is easy stuff, seriously. The design is typical for binding posts the world over and isn't some flaw Radio Shack designed or anything. As far as any hole for wire or nut or something, that's a great solution for a problem that doesn't exist. Any non-solder joint is susceptible to loosening due to vibrations and thermal cycling, even in calm environments; if you're to the point of having to worry about solder joint failure, you're obviously not going to be sourcing from Radio Shack. Just solder the darn thing and don't be an idiot.

                              After 2 hours trying to make this stupid thing work, I've decided there is NO PRACTICAL WAY provided to connect the post opposite the banana jack to anything! No slot, no hole in the post to slide a wire thru, no screw down nut, NOTHING, just a tiny slick little post sticking up in the air! I suppose if you were REALLY REALLY good at soldering, you could solder the [*] thing to a wire, but you'll need two sets of hands to hold the wire to the [*] post! On a scale of one to 10, this is a MINUS 50! If I hadn't destroyed it trying to ADAPT IT TO WORK, with other parts I added, and if the store was 20 minutes away, I'd return it to the store, DEMAND MY MONEY BACK and let a HUMAN BEING AT R/S know this story!! And no I haven't included any profane, inflammatory or copyrighted comments, but I SHOULD HAVE!
